# Values vs Messages
Publication/Inputs Values | Endpoint |
|---|---|
| Fixed routes at initialization | Routes at transmission time |
| 1 to N relationship (publications) N to 1 relationship for Inputs | All endpoints are routable - Unless otherwise specified |
| Values exist until updated | Destination specified |
| Default values | Rerouting/modification through filters |
| Associated units | Data exists as singular blobs - No records kept |
| No direct request mechanism | May define a message time - Act as events |
Other Notes:
- Endpoints can subscribe to publications to get a message for each data point
- Both can be nameless to be non-routable from outside the defining federate
